The technology group Wärtsilä introduces its latest engine and power plant solution to the power generation markets. The Wärtsilä 31DF multi-fuel engine offers unequalled open-cycle efficiency, fuel choice flexibility, and unparalleled dynamic operational features. It offers an excellent solution for markets where a gas supply is anticipated but not yet available, or where there are concerns regarding the availability or price of gaseous fuel.
The Wärtsilä 31DF engine is specifically designed for two-stage turbo charging and comes with world-class efficiency in open-cycle configuration. It delivers an output of 11 MW. The diesel version of the Wärtsilä 31 engine for ship propulsion has been recognized by Guinness World Records as being the most efficient 4-stroke diesel engine in the world.
The high efficiency of the engine reduces fuel consumption and costs, while minimizing carbon emission levels. The level of efficiency is retained even in partial load conditions, and the engine can resist output de-rating when operating in hot and humid conditions.
“This new engine is well proven already in marine applications, and is now a conversion-ready solution for the energy sector. The key word to describe its functions is flexibility, meaning not only fuel flexibility but also operational flexibility to enable a variety of operations, including load following, balancing and flexible baseload.
In all cases, the level of efficiency is outstanding,” says Antti Kämi, Vice President, Engine Power Plants, Wärtsilä Energy Business.
